Abstract
An implant receiver includes a member having an inner surface defining an implant cavity configured for disposal of a spinal implant and an outer surface. A cap includes a mating surface connectable with the outer surface such that the cap is fixed with the member and the implant is movable relative to the inner surface. In some embodiments, implants, systems, instruments and methods are disclosed.
Claims18
An implant receiver comprising:
- a member comprising a proximal portion and a distal portion removably coupled to the proximal portion, the proximal portion including an inner surface and a threaded outer surface, the inner surface defining a portion of an implant cavity, the implant cavity being configured for disposal of a spinal implant, the distal portion comprising an inner surface defining an aperture;
- a crown disposed in the aperture such that a proximal surface of the crown directly engages the inner surface of the distal portion and defines a portion of the implant cavity;
- and
- a cap including a body, a projection and a flange, the projection and the flange each extending from the body such that the flange extends about the projection, the flange having a threaded inner surface connectable with the threaded outer surface to couple the cap with the member such that the projection is positioned in the implant cavity and the implant is movable relative to the inner surface of the proximal portion.

An implant receiver comprising:
- a member comprising a proximal portion and a distal portion removably coupled to the proximal portion, the proximal and distal portions each being monolithic, the proximal portion including spaced apart arms having threaded outer surfaces, inner surfaces of the arms defining a portion of an implant cavity, the implant cavity being configured for disposal of a spinal implant, the distal portion comprising an inner surface defining an aperture;
- a monolithic crown disposed in the aperture such that a top surface of the crown directly engages the inner surface of the distal portion and defines a portion of the implant cavity;
- and
- a monolithic cap including a body, a central projection and a circumferential flange, the projection and the flange each extending from the body such that the flange extends about the projection and the flange is spaced apart from the projection by the body, the flange having a threaded inner surface configured for engagement with the threaded outer surfaces to couple the cap to the proximal portion such that the projection is positioned in the implant cavity, the projection having a threaded outer surface, the threaded outer surface of the projection facing the threaded inner surface of the flange.

An implant receiver comprising:
- a member comprising a proximal portion and a distal portion removably coupled to the proximal portion, the proximal and distal portions each being monolithic, the proximal portion including spaced apart arms having threaded outer surfaces, inner surfaces of the arms defining a portion of an implant cavity, the implant cavity being configured for disposal of a spinal implant, the distal portion comprising an inner surface defining an aperture;
- a crown disposed in the aperture such that a top surface of the crown directly engages the inner surface of the distal portion and defines a portion of the implant cavity and a bottom surface of the crown defines a cavity configured for disposal of a head of a screw shaft;
- and
- a monolithic cap including a body, a central projection and a circumferential flange, the projection and the flange each extending from a distal end of the body such that the flange extends 360 degrees about the projection and the flange is spaced apart from the projection by the body, the flange having a threaded inner surface of the cap that engages the threaded outer surfaces to couple the cap to the proximal portion such that a planar distal end of the projection is positioned in the implant cavity, the cap being monolithic.
